Patent GB-1544795-A (GB)
Title: Device for storing and dispensing a liquid product
IPC: B65D47/34
Filed: 1978-01-16
Abstract: A non-refillable dispensing container, the product in which is dispensed by a removable dispensing pump. A connector fixed in the container neck includes a fitting connecting the inlet of the pump to the interior of the container to dispense the liquid product when the pump is operated. When the pump is removed, the connector blocks the container neck against practicable refilling.
Patent GB-571209-A (GB)
Title: Process for altering the composition of fats and fatty oils for food and other purposes
IPC: C11C3/08
Filed: 1943-02-02
Abstract: The rearrangement of fatty acid radicles in a glyceride is effected by subjecting a mixture of a fat or fatty oil with fatty acid to a fractional distillation, whereby the more volatile fatty acids are removed, leaving the less volatile fatty acids to take their place in the glyceride molecule.  Thus, tripalmitin may be converted to triolein by distilling palmitic acid from the mixture of tripalmitin and oleic acid.  The treatment may be carried out in the presence of substances, such as the oxides of aluminium, magnesium and zinc, which catalyse the rearrangement, and may be conducted, preferably at subatmospheric pressure, in the presence of inert gases such as steam, nitrogen or carbon dioxide.  The treatment may, if desired, be followed by caustic refining, hydrogenation or deodorisation.  In an example, palmitic acid is distilled from a mixture of palm oil and palm oil fatty acids.  The palm oil fatty acids may be produced by saponifying palm oil and then acidifying the saponified material, but alternatively the mixture to be distilled may be produced by partially hydrolysing palm oil.  The treatment may be applied to animal, vegetable and marine fats and oils such as tallow, cotton seed, coconut oil, palm kernel oil, soya bean oil, fish oil and whale oil.  The treatment may be employed to soften or reduce the melting point of some fats, for instance, in the production of shortening, or to harden or increase the melting point of others, for instance, in the production of a confectioner's hard butter-like substance.  It may also be employed to improve the drying properties of oils.

Title: Improvements in apparatus for automatically controlling direct electric current at precise values
Inventor: GALL DOUGLAS CRISP
IPC: G05F1/56
Filed: 1961-01-16
Abstract: 932,174. Automatic current control. H. TINSLEY & CO. Ltd. Jan. 16, 1962 [Jan. 16, 1961], No. 1784/61. Class 38 (4). [Also in Group XL (c)] A highly stabilized direct current is supplied to a load from a battery through a series transistor which is controlled by a high-gain photoelectric amplifier. The battery 1 supplies the load 2 through a transistor 4 and a precision resistor 6. The voltage drop across the resistor 6 is opposed by the E.M.F. of a standard cell 12 and the resultant applied to a sensitive mirror galvanometer G1 over contacts A 1 , A 2 . (Assume all switch contacts to be in the opposite condition to that shown.) In the null position of galvanometer G1, two phototransistors 27, 28, mounted close together are equally illuminated. These photo-transistors form, with resistors 25, 26, a bridge having a battery 29 across one diagonal. Any deflection of the galvanometer G1 unbalances this bridge and so deflects a second mirror galvanometer G2 which is connected in series with resistors 18, 20 across the output diagonal of the bridge. Part of this output is fed back to galvanometer G1 through resistor 19 and capacitor 17. The galvanometer G2 proportionally illuminates a photo-transistor 8 which controls the transistor 4 and hence the current in the load 2. A capacitor 38 provides a rate feedback signal to the galvanometer G2. To protect the sensitive galvanometer G1 from overload, the circuit is initially set up manually to approximate balance by changing over all the switches to the positions shown so that the galvanometer G2 compares a portion of the voltage drop across resistor 6 with a voltage from a manually adjustable bridge 32 . . . 37.

Title: Improvements in Safety Razors.
Inventor: OSTROVSKY HARRY
IPC: B26B21/50
Filed: 1917-02-08
Abstract: 113,000. Ostrovsky, H. Feb. 8, 1917. Stropping-apparatus.-Relates to a razor which affords four different ways of stropping the blade. The twoedged blade a, Fig. 7, is clamped between holders d having pivots c, which are inserted in holes f, Fig. 6, in spring arms b on a handle c. These parts are inserted into an oblong case g, Fig. 8, open at one end .and at the top and slotted at j for the passage of the handle c, which is formed with a guide-groove l and with a second groove (not shown) above this so as to slide on the edges of the slot j; a spring tongue m has a stud, which locks into a hole o or in a similar hole lower down in the handle or stem. The case g has guard teeth p and lather collectors or ledges q. A plate u on a square spindle v, which can turn in the arms b and be pushed longitudinally against the action of a spring t, carries' detents r, which serve to hold the blade in either of its shaving positions or in an horizontal stropping position, the case g being removed prior to stropping. The blade may, however, be held in a vertical stropping position by a grooved detent s, on the plate u, extending through one of the arms b, and the case g may, if desired, be merely lowered so that the lower of the grooves l engages with it, the guard teeth p then giving the proper stropping-angle. For more certain stropping, the razor may be moved to and fro on a tightened strop introduced between the blade and one or two rollers x mounted in a three-sided frame y on the spindle v, the spindle having been turned to bring the rollers x up towards the blade. The frame is locked in this position by the detent s and in the position shown in Fig. 6 by another similar detent, a depression in the frame-end serving to receive the detents. In the stropping position of these parts, the detents r become held clear of the blade, and the ends of the frame y limit the stropping-angle. A plate or rod may be used in place of the rollers x, and, instead of the blade a clamped in the holders d, a blade in one piece resembling two hollow-ground razors placed back to back, as shown in Fig. 12, may be used. According to the earlier of the two Provisional Specifications, the blade may be arranged to be lowered in the spring arms in order to strop it.

Abstract: 286,840. Busignies, H. Jan. 25, 1927. Bearings, determining. - Two mutuallyperpendicular frame aerials C1, C2 are coupled through a condenser comprising fixed vanes L1 - - L4 and a series of continually-rotating vanes 1, 2 to a multivalve heterodyne amplifier. The rectified output from the last stage V of the amplifier is fed to a pair of coils B1, B2 mounted, as shown in Fig. 2, in the field of a permanent magnet A. The coils B1, B2 are alternately short-circuited by means of a commutator O, P, Q, R rotated at the same speed as the shaft carrying the condenser vanes, so that the coils are coupled respectively to the receiving frames C1, C<2> at frequent and regular intervals, and rotate an indicating needle Z, Fig. 2, so as to register automatically the direction of the incoming signal waves. In order to remove the 180‹ ambiguity, the oscillations received by the frames C1, C2 may be combined with those received upon an ordinary open aerial, and the indicating needle arranged to move over a complete circle instead of through a 90‹ arc as shown. The commutator in this case is adapted to connect the frames and open aerial to the amplifier during one half-circle and the open aerial alone during the remaining half-circle, the feed to the coils B1, B2 being reversed during the latter period. The centres of the receiving frames C1, C2 are connected to earth as shown in Fig. 1, whilst the terminals of the frames are connected to the fixed vanes L1, L2 and L3, L4 respectively. The moving vanes are connected to the grid of the first amplifier whilst the vanes 2 are connected to earth through a resistance R1 for purposes of symmetry. The output current from the amplifier is fed to the coils B1, B2 through a pivot-pin bearing, and through contacts immersed in concentric mercury cups respectively. The amplifier may be enclosed in an earthed Faraday cage, indicated at 2, Fig. 1.
